Situation
The following may apply:
- Dom0 may not boot at all
- Dom0 may hang during boot at the network portion
- Networking for Dom0 or DomU's may be affected negatively
Resolution
NetworkManager is a tool that allows users to configure
networking. It is especially common, and even advised, to run it on
laptops and desktops.
Xen is incomputable with the NetworkManager. NetworkManager
does not support multiple IP addresses, bonding, bridging, etc. As
a result most server admins use the traditional "ip method." On all
desktops and servers that are running Xen, the following conditions
must be true (variations from the following will result in limited
support or the server may not be able to run Xen):
- A static IP address must be assigned to Dom0
- Network manager must be disabled
- The hardware needs to be "Yes Certified"
To disable it, do the following:
- Open /etc/sysconfig/network/config for editing
- Find the following line:networkmanager="yes"
- Change it to:networkmanager="no"
- Reboot
